IPC: C10G45/08
Filed: 1991-03-19
Abstract: PURPOSE: To adjust sulfur content of a presulfurization catalyst and after activation in the presence of hydrogen to increase a fixed sulfur quantity and also to reduce an exothermal phenomenon during the activation by adding elementary sulfur to a sulfurization agent at a treatment of the catalyst by specialized sulfurization agent used as a solvent in a solution in the absence of hydrogen. CONSTITUTION: The catalyst is treated in the absence of hydrogen by at least one sulfurization agent which is used as the solvent in the solution and expressed by the formula; R-S(n)-R' (where (n) is an integer of 3-20, R and R' are the same or different, each organic group containing 1-150 carbon atoms per molecule selected from the group consisting of linear, branched, or naphthenically saturated or unsaturated alkyl group, aryl groups, alkylarly groups or arylalkyl groups; and R' can also be hydrogen atom).

IPC: B65H29/56
Filed: 1988-03-10
Abstract: PURPOSE:To prevent a leak between a transfer device and a separation device by applying both devices with AC voltages which are equal in frequency and in phase with each other. CONSTITUTION:The AC voltages applied to a transfer corotron 30 and a separation corotron 32 are so controlled that they are equal in frequency and in phase with each other. Consequently, the difference between the voltage waveform applied to a transfer corotron wire 30a and the voltage waveform applied to a separation corotron wire 32a is invariably constant. The value corresponds to the difference between DC bias voltages which are applied by DC power sources 36 and 40 and is extremely small. Further, the current leakage between the transfer corotron 30 and separation corotron 32 is securely prevented.

Abstract: PURPOSE:To enable to lower fuel consumption and to purify the exhaust gas, by sucking and compressing fuel from a fuel jet together with air by a pump, and distributing fuel after atomizing the fuel by ejecting the same from an orific. CONSTITUTION:Fuel from a fuel jet 10 is sucked into a pump 17 via a restriction 12 and an air passage 13 together with air supplied from a fuel discharge chamber 11. Here, since fuel supplied from the fuel jet 10 is ejected only by the function of the difference of fuel level in a float chamber 15, the fuel flow rate is kept constant independently of the air flow rate. Thus, fuel is metered by a metering needle 9 and the fuel jet 10 to suit to the air flow rate and sucked into the pump 17 while being mixed with air supplied from the air passage 13 via the restriction 12. Fuel compressed by the pump 17 is then supplied to an orifice 19. When fuel is ejected from the orifice 19, it is atomized into fine particles and distributed uniformly by a distributing section 20. Further, when fuel is ejected from a nozzle 24 together with compressed air, fuel is atomized into finer particles.

Title: Dwell controlling method of injection molder
Inventor: SHIROGANEYA TSUKASA
IPC: B29C45/77
Filed: 1989-03-10
Abstract: PURPOSE:To obviate the dispersion of quality from occurring since the kick-off of molding by a method wherein corrected dwell pressure, which is obtained in the molding of conforming item, is re-corrected during the same shot in proportion to the magnitude of the difference between the mold temperature at every shot and the set temperature at the molding of conforming item so as to control the dwell pressure in order to keep the maximum in-mold pressure constant over the whole shots. CONSTITUTION:The moving time of a moving body and the mold temperature are respectively set in advance in a setter as the set dwell pressure, the set time and the set temperature T0. Through the Time-P control, corrected dwell pressure P0 is obtained. With a temperature sensor T, the mold temperature Tm at the time point of injection start is detected. The mold temperature Tm and the set temperature Ts, which is set in advance, are compared with each other. When the temperature Tm is higher (or lower) than the temperature Ts, a re-corrected dwell pressure P1, which is smaller (or larger) than the corrected dwell pressure P1 by the pressure DELTAPT1, which corresponds to the temperature difference, is a adopted as the dwell pressure in dwell pressure application process PD. Accordingly, the maximum in-mold pressure at every shot can be kept nearly constant regardless of the fluctuation of mold temperature.
